About Henan Quanshun Flow Control Science And Technology Co. Ltd. - Industrial Valves & Gauges Supplier in China

China hosts Henan Quanshun Flow Control Science And Technology Co. Ltd., which lists eight distinct valve and machined component products in its catalogue. The company classifies its offerings under the top categories "Industrial Valves & Gauges" and "Machined Components," indicating a focus on flow‑control hardware for process and water‑handling applications. The eight items include a soda ash double eccentric semi‑ball valve, sand casting valve parts, a water pump control tube force valve, an angle‑pattern globe type isolation valve, a spherical disc butterfly valve, a disc‑type tank bottom angle valve, a wedge gate valve, and a slurry valve. All products fall within the HS‑code families for valves (typically 8481) and gate‑type valve parts (8482), which are the standard customs classifications for such equipment.

The catalogue shows a mix of ball, globe, butterfly, gate and specialty slurry valves, each designed for different media and pressure ranges. While the supplier does not disclose material grades, the product types correspond to common industry specifications such as API 6D for ball and gate valves and ISO 5208 for globe and butterfly valves. Typical pressure ratings for these valve families range from 0.6 MPa (Class 150) up to 1.6 MPa (Class 300), and nominal diameters usually span DN 15 to DN 300. The inclusion of sand‑cast valve parts suggests the company also provides custom‑machined components that can be integrated into larger valve assemblies.

Product Range and Specialties of Henan Quanshun Flow Control Science And Technology Co. Ltd.

The eight catalogue items cover the principal valve architectures used in chemical, water‑treatment and bulk‑material handling sectors. A double eccentric semi‑ball valve is commonly employed for high‑flow, low‑torque service, while a spherical disc butterfly valve offers quick shut‑off for large‑diameter pipelines. Angle‑pattern globe valves provide precise throttling, and wedge gate valves are typical for full‑open/close isolation. The slurry valve is specialised for abrasive media, often fabricated from hardened alloy or coated steel. In the broader market, these valve types are offered in carbon steel, stainless steel (e.g., 304/316), and sometimes ductile iron, with pressure classes ranging from PN 10 to PN 40 and end connections such as flanged, threaded or welded. Industry standards for these products include API 600 for resilient‑seat gate valves, API 609 for ball valves, and IEC 60534 for globe valves. Buyers frequently request compliance with ISO 9001 quality management systems and CE conformity for equipment destined for the European Union. Typical product documentation includes mill‑test reports, pressure‑test certificates and dimensional drawings.

Trade and Export Information - Henan Quanshun Flow Control Science And Technology Co. Ltd.

China is among the world’s largest exporters of industrial valves, supplying Europe, the Middle East, Southeast Asia and Africa with equipment that complies with HS chapter 84 (particularly codes 8481 and 8482). Export shipments are usually packed in wooden crates or bulk‑packed in 20‑ft or 40‑ft containers, with protective padding for delicate valve bodies. Commonly required certifications for Chinese valve exporters include ISO 9001, CE marking under the Pressure Equipment Directive (PED), and where applicable API or ASTM certifications. Importing countries often request a Declaration of Conformity and a test report confirming compliance with the specified pressure class and material standards. Standard Incoterms used are FOB (Port of Shanghai, Ningbo or Guangzhou) or CIF to the buyer’s destination port, with customs documentation covering HS codes, country of origin and value declaration.

Sourcing from Henan Quanshun Flow Control Science And Technology Co. Ltd. - Buyer Guidance

When sourcing valves from this supplier, request the current ISO 9001 certificate and any CE or API certificates that apply to the specific valve type. Ask for a mill‑test report that details the chemical composition and mechanical properties of the valve body material, as well as a pressure‑test report confirming the rated class (e.g., PN 16 or PN 25). Verify the connection type (flanged, threaded, welded) and size (DN 15‑DN 300) against your system drawings before placing an order. Samples of critical valve sizes are often supplied in limited quantities; confirm the sample lead time and any associated shipping charges. Typical minimum order quantities align with container loads - approximately 5 000 kg for small‑diameter valves or a full 20‑ft container for larger units. Lead times after order confirmation range from 30 to 45 days, depending on machining complexity and any required surface treatments such as coating or painting.

What valve families are included in Henan Quanshun’s catalogue?

The catalogue lists semi‑ball, globe, butterfly, gate and specialised slurry valves, together with sand‑cast valve parts for custom assemblies.

Which HS codes apply to these products?

Industrial valves are generally classified under HS code 8481, while gate‑type valve parts fall under HS code 8482.

What material standards should a buyer verify?

Typical materials are carbon steel, stainless steel (304/316) or ductile iron; buyers should request mill‑test reports confirming compliance with ASTM A216, A351 or equivalent standards.

Which certifications are commonly required for these valves?

Buyers usually require ISO 9001 quality certification, CE marking for EU markets, and where applicable API 600/609 certifications for gate and ball valves.

What are the usual pressure classes for the listed valves?

The valves are commonly offered in PN 10 (0.6 MPa) to PN 40 (2.5 MPa) classes, corresponding to API Class 150‑300 pressure ratings.

How are the valves typically packaged for export?

Standard export packaging uses wooden crates with internal bracing, or bulk packing in 20‑ft or 40‑ft containers, with moisture‑resistant liners for corrosion‑sensitive components.

What documentation should be requested before purchase?

Request the supplier’s ISO 9001 certificate, CE Declaration of Conformity, mill‑test report, pressure‑test certificate, and detailed dimensional drawings for each valve size.

What are typical lead times and minimum order quantities?

Lead times are usually 30‑45 days after order confirmation; minimum orders often correspond to a full container load, roughly 5 000 kg for small‑diameter valves or one 20‑ft container for larger units.
